BRACKET.

SPECIFICATION forming part of Letters Patent No. 482,086, datedSeptember 6, 1892.

Application filed April 26, 1892.

To all whom it may concern.-

Be it known that I, WILMER D. GRIDLEY, of Brooklyn,in the county ofKings and State of New York, have invented a new and useful Improvementin Brackets, of which the following is a specification.

My invention relates to an improvement in brackets comprising astationary and an adjustable section, provided with means to lock thearticle to be held to the adjustable section, for locking the adjustablesection to the stationary section in its various adjustments, and forlocking the stationary section to the wall or other support, so that theparts may be readily assembled, adjusted, and separated at pleasure.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Figure 1 represents the parts inassembled adjustment in side elevation and' partly in section. Fig. 2 isa top plan view showing the parts assembled, the stationary part of thebracket being shown in section and the looking device on the adjustablepart being shown in full lines in released adjustment, its position inlocked adjustment being represented in dotted lines; and Fig. 3 is aview in detail, in front elevation, of the stationary part of thebracket or wall section, showing its looking device in releasedadjustment and the bracket-section itself in the position which itassumes while being adjusted or removed from the screws or otherfastening devices by which it is secured to the wall.

The stationary or wall section of the bracket is denoted as a whole by Aand the adj ustable section or supporting-arm is denoted as a whole byB. The part A is bifurcated at its lower end,terminating in legs CLa,gradually separating from each other to receive between them the shankof the fastening devicesuch,for example, as the screw Oand at the lowerends of said legs a a are outwardly-turned feet a and a The legs a, anda not only gradually diverge from each other, but also are offset fromthe back of the part A, so as to stand out a short distance away fromthe wall, thereby enabling the feet a and a to form a convenient supportfor suspending therefrom, by a wire or other'flexible connection, apicture or other ornament. The said Serial No. 430,661. (No model.)

part A is further provided with an opening a at its upper portion forthe reception of the head of a second fastening device-as, for example,a screw O-and a contracted slot a leads upwardly from said opening a forthe reception of the shank of the said fastening device O. Intermediateof the openings for the reception of the fastening devices the said partA is provided with a socket portion a for the reception of the pintle ofthe adj ustable or supporting section. At the rear of the socket portiona the bracket is provided with a recess a for the reception of a nose orrib on the pintle of the supportingarm for holding the latter in itsposition squarely to the front, and on opposite sides of said recess athere are formed raised portions a and a? for engaging said nose or rib,and thereby holding the supporting-arm in its adjustment swung to theright or left, as may be desired.

A locking device consisting of a swinging latch D is pivotally secured,as at d, to the upper portion of the part A and is adapted to swing intoposition,so that its lower end Wlll be in proximity to thesupporting-arm when the parts are assembled, and thereby prevent it fromescaping out of its socket, as clearly shown in Fig. 1. The latch D isfurther provided with a rearward-extending lip 61', (see Fig. 1,) whichwhen the latch is thrown into its locking position projects under thelower side of the head of the screw 0, and thereby prevents the liftingof the part A to remove it from the wall.

The adjustable section or supporting-arm B is provided with apintleportion b, adapted to enter within the socket portion a of thestationaryportion, and said pintle portion 1) is provided with arearward-projecting nose or rib b for engaging the recess a or theraised portions on the opposite sides of the recess to lock thesupporting-arm to the front or to one side or the other, as maybedesired.

The form of supporting-arm which I have chosen to represent as myinvention is provided at its free end with a circular skeleton rest 17provided with fixed retaining-lips b at intervals thereon for thereception of the base 6 of a lamp or jar E. A swinginglatch F is pivotedto the shank of the arm -B, as at f, and when swung into lockedposition, as

ICO

shown in Fig. 1, its end is adapted to overlap the rest 19 and, togetherwith the stationary lips b serves to securely hold the lamp or othersupported article to the base. The latch F is provided at its oppositeend with an operating-handle f, which is in effect a gravity-catch, andis pivotally secured to the latch F, as at f so that it may be swung ina vertical direction or in a direction at right angles to the swingingmovement of the latch F. The catch f is provided on its under side witha nose f adapted to enter a recess 19 in the upper face of the arm B,and when in such position (represented in full lines in Fig. 1) thelatch F will be securely locked against displacement from side to side.When, however, it is desired to remove the article supported, the catchf may be lifted into the position shown in dot-ted lines in Fig. 1, andthe latch F may be then swung to the right or left to permit the base ofthe article supported to be removed from the rest b In order to providefor securing the wallsection to the wall against removal, except bylooseningits fastenings, I find it desirable to form shoulders h inproximity to the end of the opening between the legs a and a of thebracket, preferably by recessing the bracket in the neighborhood of theupper end of said opening, as indicated in Fig. 3, so that when theshank of the screw has been adjusted in the upper end of said openingthe screw 0 may be screwed home into contact with the bracket, and theswelled portion of the screw on the under side of its head will therebybe forced into engagement with the shoulders h, so that it will beimpossible to remove the section A, even after the latch D is released,without again loosening the screw 0, so as to permit the bracket to heslid upwardly along its shank.

What I claim is 1. The combination, with the supportingarm of a bracket,of a latch for locking the article to be held in its seat and a catchpivoted to and carried by the latch for holding the latch in lockedadjustment, substantially as set forth. I

2. The combination, with the supportingarm of a bracket, of a latch forlocking the article to be held in its seat, and a catch pivoted to andhaving a swinging movement transverse to the movement of the latch, thecatch and the supporting-arm being provided the one with a recess andthe other with a projection adapted to engage the recess and therebyhold the latch in locked adjustment, substantially as set forth.

3. The combination, with a supporting'arm section and the wall-section,the one provided with a pintle and the other with a socket, thewall-section being further provided with an opening therethrough at apoint above the pintle and socket for the adjustment of the wall-sectionon and its removal from a fixed fastening device at pleasure, of a latchpivoted to the wall-section and adapted to swing into position oversaidopening through the wall-section to lock the pintle in the socket,substantially as set forth.

4. The combination, with the wall-section provided with an openinghaving a contracted neck to receive a fastening device, of a swing inglatch pivotally secured to the said wallsection and provided with a lipadapted to overlap the head of the fastening device and prevent theaccidental displacement of the wall-section, substantially as set forth.

5. The combination, with the wall-section provided with an openinghaving a contracted neck to receive a fastening device and with asocket, of a supporting arm having a pintle adapted to enter the saidsocket and a latch provided with a lip and adapted to swinginto positionto simultaneously lock the pintle in its socket and wall-section to itsfastening device, substantially as set forth.
